State management: other; state financing of activities or services required of local units of government; provide for. Implements sec. 29, art. IX of the state constitution & repeals 1979 PA 101 (MCL 21.231 - 21.244).

HB 5248, titled the "Headlee unfunded mandates prohibition act," requires the state to fully finance costs for local governments when mandated by state law to provide new or expanded services. It defines "state requirement" as a new or increased service beyond existing law, excluding trivial costs (under $300 per claim) or situations where the mandate offsets existing costs. The bill directly affects cities, counties, school districts, and other local units of government by ensuring the state covers these mandated expenses rather than leaving them to local budgets. Key provisions include requiring state agencies to calculate and fund "necessary costs" for mandated activities, while exempting minor or offsetting cost mandates.
